SAMUEL MASON, OF NORTHFIELD, CONNECTICUT, ASSIGNOR TO THE NORTHFIELD KNIFE (10., OF SAME PLACE.

'- lMPROVEM'ENT'lN POCKET-KNIVES.

Specification forming yart of Letters Patent No. 86,32 I, dated Augu 1562- To all whom it may concern:

Be it known that I, SAMUEL MASON, of

N orthfield,in the county of Litch field and State of Connecticut, have invented a new and useful Improvement in Pocket-Knives; and Ido hereby declare that the following is a full,-

view ofthe same. I

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists. in constructing the handleof the knife of malleable cast-iron and with a corrugated external surface in imitation of buclrhormwhereby a much more durable lgnifegis obtained than any hitherto con structed, and one which may be ma'nu factu red at a less cost. I

To enable those skilled in the art to fully understand and construct my invention, Iwill proceed to describe it.

A represents the blade of the knife, B the handle, and O the spring, which is secured by rivets a between the two parts I) I) of the handle, and bears against the pivoted end of the blade, as usual. The two parts I) b of the handle are of malleable cast-iron, their inner surfaces being smooth and their outersurfaces being rough or corrugated like buckhorn, the mold in which the parts b are'cast being made in proper form to produce this result. One of the parts,- I)", is cast with a smooth surface, 0, for the n'ame of the owner to be engraved on it, and a smooth surface,-d, is also cast at the ends of the parts I) b in imitation of a bolster, which is employed in the ordinary knife handles.

Bythus constructing the knife it will be seen that the ordinary metal plates necessarily used as a liring are dispensed with, as well as 1 the labor and expense of fitting the bnckhorn thereto, while a very strong and durable handle is obtained.

Buekhorn forms the most desirable material for. the handle of an ordinary pocket-knife,

' ers, laborers, 86C. Ordinary gray or cast iron would be liable to break under this operation, but not the malleable cast-iron.

I do not claim, broadly, a knife provided witha cast-nietalhandle irrespectiveof the material used; but.'

I do claim as new and desire to secure by Letters Patent -As an improved article of manufacture, a pocket-knife having a handle of malleable cast-iron, with a rough or corrugated. exterior, in imitation of b'uckhorn, as herein set forth.

SAMUEL MASON.
